The influence of diet on breast milk microbiota pdf

There is currently an increasing interest on the bioactive components that elicit the protective capacity of BM during the first months of life immunoglobulin A, lactoferrin, lysozyme, mucine, lactadherin, anti-inflammatory and antioxidant components, oligosaccharides, glycoconjugates and microbial factors.

These studies strongly suggest that diet can influence the intestinal microbiome and disease burden. PubMed Google Scholar 6. The breast milk influence on initial intestinal microbiota also prevents expression of immune-mediated diseases asthma, inflammatory bowel disease, type 1 diabetes later in life through a balanced initial immune response, underscoring the necessity of breastfeeding as the first source of nutrition.

In sum, breast milk not only modifies the environment of the infant gut to protect against pathogenic bacteria, it also facilitates colonization with commensal bacteria that promote short- and long-term immune health of the host. These two examples underscore the importance of bacterial colonization in the development and maintenance of mucosal immune function.

Impact of lactation stage, gestational age and mode of delivery on breast milk microbiota

Science ; In a seminal study that underscores how colonizing bacteria influence intestinal protective function, germ-free mice were colonized with a single human intestinal commensal bacterium, Bacteroides thetaiodamicronm, and after colonization the intestinal epithelial RNA was analyzed for altered gene expression Rautava S, Walker WA.

This study illustrated how initial bacterial colonization affects the small intestine of newborns at birth, since the newborn infant is like a germ-free rodent receiving its first colonization.

In addition, B. Improper colonization, dysbiosis 3delays the process and results in increased susceptibility to newborn and infant infections and altered immune homeostasis leading to the expression of immune-mediated disease 45 and metabolic diseases 6 later in life.

The ability to modulate the development and the composition of the intestinal microbiota in order to improve health of both mother and child is the basic rationale for the use of probiotics.

These migrant intestinal bacteria are engulfed by lymphoid cells which home to the engorged breast and are then secreted into breast milk where bacteria are released. In this review, the importance of initial colonization will be reviewed and the vital contribution made by exclusive breastfeeding underscored.

Finally, in an epidemiologic study of Japanese citizens, an increased expression of a classic Westernized diseases, e. Bacteria and host interactions in the gut epithelial barrier. Therefore, differences in BM microbiota in children born by Cesarean section may contribute to the heightened risk for immune and inflammatory conditions.

During the next year, the introduction of oral feedings, e. Over the first 3 wk, the breastfed infants have a striking increase in Bifidobacteria and Lactobacillus species compared with formula-fed infants who had a more mature microbiota pattern containing organisms such as enterobacteria and enterococci.

This suggests again that gestational age or gut maturity had as much influence on the diversity of the microbiome as any dietary regimen.

Similarly, Bifidobacterium spp.

Effect of Breast and Formula Feeding on Gut Microbiota Shaping in Newborns

Escherichia coli, Enterococcus fecalis, and faecium are the most represented, followed by Klebsiella and Enterobacter, and, more rarely and transiently, Aeromonas, Pseudomonas, Acinetobacter, alpha-haemolyticus Streptococci, and coagulase-negative Staphylococci Penders et al.

To prevent continuous inflammation of the intestine due to exposure of large numbers of colonizing bacteria, the absolute expression of these receptors, particularly the luminal surface expression of TLR-2 and 4, is reduced when the neonate leaves the intrauterine environment Sudo et al.

Breastfeeding and Intestinal Colonization As stated above, nutrition is an important environmental determinate of gut microbiota. The type of feeding, through its selective action on bacterial colonization and growth, which, in turn, induce specific T cell responses and modulates substrates oxidation and consumption, has a major impact on the development of immune functions and oral tolerance Palma et al.

Exposure to breast milk during infancy appears to be particularly important in shaping the microbiome [ 8 ].

The Impact of the Milk Glycobiome on the Neonate Gut Microbiota

New clinical trials with clearly defined target populations and clinical as well as immunologic, metabolic, and microbiological endpoints may be conducted and, eventually, recommendations for clinical use to improve patient care may hopefully be devised.

There are 10 times the number of bacteria in the intestine as there are eukaryotic cells in the body and fold more bacterial genes than human genes in the body  · Objective: There is an increasing evidence of the immunological role of breast milk (BM) microbiota on infant health.

Gut and Breast Milk Microbiota and Their Role in the Development of the Immune Function

The preterm infant intestinal microbiome is influenced by postnatal time, birth weight, gestational age, and nutrition. Feeding with breast milk appears to mask the influence of birth weight, suggesting a protective effect against gut immaturity in the preterm justgohostelbraga.com by:  · Gut microbiota influence the growth and differentiation of gut epithelial cells, and play pivotal nutritive, metabolic, immunological, and protective functions (O’Hara and Shanahan, ).
